Abstract (en)
[origin: US2014160603A1] A circuit interrupter for a power circuit includes separable contacts, an operating mechanism structured to open and close the separable contacts, and a trip circuit cooperating with the operating mechanism to trip open the separable contacts. The trip circuit includes a number of hardware circuits having a processor with a number of routines. The routines provide a number of protective functions structured to detect a number of faults of the power circuit, a number of repetitive test functions for the number of hardware circuits, and a supervisory function cooperating with the number of repetitive test functions. The supervisory function is structured to prevent availability of protection by the number of protective functions from falling below a predetermined threshold as a result of a plurality of intermittent error conditions of the number of hardware circuits.
